T0` all whom t may Concern.' i

Be it known that I, JOHN Grrz, a subject of the King of Hungary, residing at Orange, y

in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Fan-Actuating Means, of which the following is a specification.

This invention relates to certain new and useful improvements in mechanical fan-actuating means.

The primary object of the device is to provide actuating means for a revoluble hand fan which is of light weight' and is readily operated with the desiredy rapidity by- -a slight pressure exerted thereon by a finger or the thumb of the holding hand'.

A further object is to provide actuating means for a revolving hand fan that iseasy to manufacture and is highly eflicientA in mechanically settingv the air in motion being provided withdriving mechanism actuated by the hand of the person supporting thel device.

A still further object is to provide in conl nection with a revolving hand fan arack and pinion actuating means for the fanadapted for actively actuating the same uponl a ydownward movement vimparted thereto by the hand of the operator holding.k

the device.

IVith these general objects in view and others that will appear fas the nature ofthe of the mechanism casing removed. Fig. 2

is a central longitudinal sectional view thereof. Fig. 3 is an elevation of the driving ,means of the device with adjacent parts shown in section and the elementsbeing positioned ready for actuation. Fig. 4l is a similar view with the elements positioned as found at thel end of an operative movement thereof. Fig. 5 is a side elevationof the elements shown in Figs. 3 and 4. Fig. 6 is a transverse sectional view upon line VI-Vl of Fig. 5. Fig. 7 lis a perspective view of the mechanism frame of the device, and

Fig. 8 isa different form of fanrthat may be employed.

Referring more in detail to the drawing it will be noted that the invention broadly consists in a fan 10 carried by a casing 11 which is provided with suitable mechanism for revolving the fan, the said casing having a removable side 12 and an end handle portion 13 and by which the device is held by the operator during the fanning operation.

The casing 11 at lthe end thereof opposite the yhandle 13 has a tubular lateral eXtension let axially of which a shaft 15 is journaled for revolution being provided with a pinion 16 withinthe casing and having one end 17 extending exteriorly thereof and upon which the fan 10 is rigidly secured by means of a winged set nut 18. The fan 10 is preferably formed of a plurality of separate blades 19 here illustrated as six in number and being separately journaled upon the shaft end 17 so that upon releasing the nut 18, the fan blades may be folded or closed together in a manner that will be at once blades, thus assisting ythe nut 18 in positioning theblades accurately spaced apart.V

A driving shaft 23 is journaled longitudinally ofthe casing 11 in opposite brackets 241 and 25 positioned respectively adjacent the tubular and handle ends of the casing. The driving shaft is provided with a termijnal pinion 2G in constant mesh with the pinion 16 of the fan shaft 15 and whereby as will be apparent, the revolving of the driving shaft 23 results in revolving the fan 10.

A stub shaft 27 is journaled in a bracket 28 and anarm 29 of thecasing bracket 25 and is provided with a large gear 30 in constant mesh with a small pinion 81 positioned adjacent the handle end of the driving shaft. A. power shaft 32 is journaled in opposite posts 33 carried by the base 34 of the casing bracket 25 and has a large gear 35l secured thereon `which is in constant mesh with a pinion 36 upon the handle end of the stub shaft 27. By this arrangement it will be seen that any rotation of the power shaft and its gear .35 will turn the stub-shaft 27 by means of the stub shaft pinion 36 and whereupon the gear 30 ofy the stub shaft will impart movement to the driving shaft 23 by means of the driving shaft pinion 31.

One of the essential features of the invention is the actuating mechanism for the power shaft 23 and the same will now be described.

A longitudinal reciprocating rack 37 is slidably mounted in a slot 38 of lavlaterally,y projecting arm 39 of the casing bracket 25 and has an actuating lever 40 pivotally connected by the bolt 41 to the top thereof while the inner end of said 'lever is pivoted as at 42 to a projecting post 43 of the bracket armlf 39 and the outwardly projecting free end of the lever is provided with a thumb or finger.. plate 44.` An expansion spring 45 encir-. cles the rack 37 and' is positioned between` the arm 39 and lever 40 and is adapted :to

hold the rack in a normal projected position and is formed with a larger convolution adjacent the arm 39 than, those whichfare positioned adjacent the lever 40 which per# mits an oscillation of the rack 37. within the slot 38 at its eXtreme outer and inner limit of bear against the rack 37 at a point betweenr Y the fingers 4G and hold the toothedrack in engagement with the said power shaft pinion during the inward movement of the rack.:

An inward movement Vof the rack being effected by pressing the thumb or linger of the hand upon the plate 44 when the handle 13 is grasped in the hand, the power shaft 32 willbe thus revolved whichr in the manner hereinbefore described will result in revolving the fan shaft 15 and thus turning thefan l0. When the rack 37 has nearly. reached its eXtreme inward limit of its stroke, the inclined end 52 of-,the rackfwill be brought in contact with the convex surface of a leaf spring 53 mounted upon'the casing 11 and a slightly continued inward movement of the rack 37 will result in a forcing of the lower end of the rackin a swinging movement by means of the said engagement of the spring 53 and rack end 52, .which movement willfbe in a direction away from the power shaft 32. This swinging movement of the rack `end places the rack plates 47 in a plane to. be received ,with in the inner grooves 54 of theY lingers 46 when the spring 45 projects the rack 37 outwardlv toits normal position, .and at which from thecasing bracket.

time the rack teeth are out of engagement with the power shaft piniony as best illustrated in Fig. 4.

o By this detailed description of the elements ofthe device and the separate operations thereof, the complete operation of the device will be at once apparent. It is to be understood that the blades of the fan are rigidly secured to the fan shaft by the nut 18 and that the removable side 12 of the casing is secured in place as illustrated in Fig. 2 and at which time the actuating. lever 40 projects through a side slot 55 ofthe said casing. side` 12.

Pressure upon the `plate 44 inwardly moves the rack 37 thereby turns the power, stub, driving1 and I fan` shafts, and at l its eXtreme inward limit of its movement. its return reciprocation is changed to bring the rack out of engagement .withk the power yshaft pinion 32 and to freelymove to its normal outward position, it beingthusunderstood that the inward ino-vement alone effects the operation ofthe fan while; the outwardmovement thereof isonly a return idle movement.v

of the rack,;although,`thefan by. itsown momentum continues its revolutions notwithstanding the interrupted vor pulsating lInanner of applying the. power thereto. y

InFig.l 8 of the .drawingsa disk y60 isprovided whiehis employed as the fanmeinber.

and is secured to the outer end of a driving shaft 23similar to the driving shaft-23 of the preferredformof construction, a sil-mie lar casing 11 beingalso employedand all of the driving and remainingmechanism be ing identical tothat hereinbefore described.

While the form of thek invention` herein shown and described is what is believed to be the preferred embodimentthereofrit is nevertheless, to beunderstood thatminorchanges may be madev without departingfrom. the spirit and scope thereof as claimed.
